PICTURE-FRAME.

SPECIFICATION forming part of Letters Patent N0. 752,283, dated February 16, 1904. Application filed January 2, 1902. Serial No. 88,232. (No model.)

To alt whom it may concern:

Be it known that I, Guess Conn, manufacturer, of 3 Koenigsplatz, Breslau, in the Empire of Germany. have invented an Improvement in the Manufacture of Picture-Frames; and I do hereby declare the nature of this invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement.

This invention relates to picture-frames, and has for its object to provide a frame of simple construction and having the appearance of a solid frame, which can be readily folded flat for storing and packing.

A picture-frame made in accordance with my invention comprises a back part, a front part, and a side part to represent the thickness. The corners of these parts for forming the frame are so cut away or stamped out as to enable the said parts to be bent forward or folded in' such a manner as to set the part representing the thickness of the frame either at right angles or an obtuse angle with both the back and the front or face of the frame, and thus form a solid-looking frame.

The invention will be readily understood with reference to the accompanying drawings, in which Figures 1, 2, and 3 are perspective views of frames made in accordance with my invention. Figs. 4 and 5 are details showing the construction of the corners of frame shown in Fig. 3. Figs. 6' and 7 are details showing a modified form of corner. Fig. 8 isaperspective view of a modified form of frame made in accordance with my invention. Figs. 9 and 10 are details showing how the corners thereof may be formed. Figs. 11, 12, and 13 are details showing another modified form of corner. Figs. 14 and 15 are details of another modified form of corner, which is provided with means of fastening the folds thereof in position. v r

The folds or grooves or the like around the middle part a may be parallel or inclined, so that the back may be parallel to the face or front, as shown at Fig. 2, or inclined thereto, as indicated at Fig. 1. When the back is parallel, the outer part or face of the frame will project everywhere with an equal distance from the back a, but when inclined at an angle this projecting distance varies, and theframe will stand out from the back at a certain incline. A

To enable the frame to be formed for use, its corners must be specially formed,although it is n0t in-all cases necessary to actually out the corners, as they may be grooved, folded, and pressed or otherwise treated to admit of mounting the frame. This may be effected, for example, as indicated at Figs. 3, 4:, and 5, by cutting or stamping a square portion d out of each corner of the side parts or strips 6 and c, as shown, so that after erecting the frame the front'parts or strips 6 and f project parallel with the back and have projecting squares g at the corners. These projecting squares at the four corners-of the frame impart to it the appearance of an ordinary solid frame.

According to another construction, which is 7 shown in Figs. 6 and 7, a similarlyfolded projecting corner is formed by making a'diagonal incision it, so as to divide the part cl, Fig. 5, into two triangles i in, Fig. 7, while a groove in the direction of the other diagonal of each such square enables the triangular portions 1'- and k/to befolded rearward. By thus fold ing the said triangular portions the frame is enabled to assume its solid form for use, inasmuch as the folding of the lower triangle it causes the frame part b 0 to project forward, and the folding of the triangle z causes the corner square g to advance from the remaining parts of the frame. It is now only required to apply the requisite adhesivamaterial to the folded triangular pieces 2 in, and thus secure the frame permanently in its position for use. By following a similar method I such frames may also be manufactured without cutting away any of the material of the frame, as will be readily understood by reference to Figs. 11, 12, and 13, of which Fig.

13 shows the blank prepared from a card-- board piece and in which the full and the dotted lines mark the grooves formed on the obverse and reverse thereof. Fig. 12 shows theframe in one of the stages of folding, while Fig. 11 shows a perspective view of one corner of the finished frame. The frame parts 6 0 are formed with cross grooves or folds Z m, with three corners, from each of which latter three parallel folds or grooves n o 1) part. In order to give the frame its proper form, it is only necessary to bring the surfaces limited by the lines m and 7), respectively, and common central line close together, thereby causing the parts 0 to project forward and the'outer parts (2 f to advance from the back.

According to the construction shown in Figs. 8, 9, and 10 an obtuse triangle 9 is cut out at the corner of the parts 7) a, and from the corners thereof extend diverging folds or grooves in lieu of the parallel folds or grooves shown in Figs. 11 to 13. In this case the placing together of the folds or grooves 72 p in order to obtain the solid frame will cause the outer parts e f thereof to project with an incline either forward, as in Fig. 11, or rearward of the parts 6 0, as in Fig. 3, and with an even or flat corner. It is advantageous to cut away the corner 1- in the latter form, so as to avoid rearwardly-projecting corners with the inwardly-bent frame parts ef.

Obviously the last-described form of frame may also be obtained by cutting the parts ef at the cornersthat is to say, in 'the form shown.in Figs. 8 to 13 the corner portion of the parts ef between the fold or grooves up may be entirely removed; but while obtaining the same form of frame it will be necessary to provide separate means for securing the corners. Suitable means for thus fastening the cut-away corners may consist, for example, of staples or the like. The fastening means for the corners of the frame may, if desired, be provided by stamping or cutting the corners with tongues s and slits t, as shown at Figs. 14 and 15, to enable the frames to be delivered in a flat condition and to be readily mounted for use when required without the aid of extraneous means for keeping it together. Theessential feature of providinga frame in a single piece adapted to be kept in a flat condition till required for use exists in all the various forms shown in the annexed drawings, although only the form shown in Figs. 14 and is provided with fastening means, while the other forms of construction require to be secured by separate fastening means.

The part a or back of the frame may be of any desired form, such as square or polygonal, and may even have slightly-curved limited lines, in which case the folds or grooves may have cuts, incisions, or the like where required.

It will be seen from the above that the back a is surrounded by side strips or parts (2, arranged at an angle thereto, and these side strips are bordered by outwardly-extending front strips or parts a f, arranged substantially parallel to the back a, and each of these front strips is connected with the similar strip on the adjacent edge of the frame, or, in other words, the front strips are connected at the corners by integral portions.

I do not wish to limit myself to the manner of ornamentating the rim, as this may be done by painting or in other suitable ways. The picture is secured to the frame by, for instance, gluing it to the central part (1.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what Iclaim is A picture-frame composed of a back 1/ of substantially rectangular form, having integral side strips around the margin thereof extending up at an angle thereto and with outwardly-extending front strips bordering and integrally connected with the side strips, the said front strips being connected with each other by integral portions at the corners.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GEORG- JOHN.
